A while back I bought a Dragonstorm so I could use a head for Zeta Prime.
The leftovers I turned into a movie-style Doublecross and an attempt at a snake.
Just recently I got a hankering for a screen accurate Stormreign so painted the snake-bot red and put the original head on.
I then put a junker movie Optimus head on the other bot but then thought "hmmm, a movie Optimus that combines with another bot for a flying mode..."
So I swapped heads again and found a junker movie Jetfire head.
It just sits on the torso in bot mode but that's all it needs to do.
